Kapok fiber (Ceiba pentandra) is a potential source of cellulose, but its utilization is still minimal. This study aims to isolate nanocrystalline cellulose (NCC) from kapok fibers using acid hydrolysis at various times and characterize its properties as reinforcement for alginate‐nanocrystalline cellulose (Alg‐NCC) hydrogel beads. NCCs are characterized using various techniques, and hydrogel beads...
